Over the last years, our laboratory has devoted a lot of efforts into gold(I) homogeneous catalysis.^[1] For that purpose, we have developed new gold(I) complexes using unusual phosphorus based ligands. Thus, we have prepared secondary phosphine oxide (SPO) complexes and fully characterized them. The latter were engaged in diagnostic catalytic reactions involving various polyunsaturated precursors.^[2] Aiming at asymmetric catalysis, we also designed some new dinuclear gold(I) complexes based on an allenic bis-phosphine ligand which coordination properties were completely undescribed.^[3] First examples of enantioselective transformations will be presented.
